JEFFSY is ready to be your new bro and wingman. You’re going to be the new dream team. Whether on your home trails or crossing high mountains, JEFFSY scales the toughest peaks with unbelievable drive and traction, and inspires you to unexpected performances. JEFFSY lets you discover the most remote locations, climb the highest peaks, and keep it pinned on the way back down. Because JEFFSY is the YT of All Mountain bikes, it won’t hold you back even in the roughest terrain. Thanks to its gravity oriented geometry JEFFSY remains agile and playful, even with the 29” wheels. And to meet our high design standards we gave JEFFSY super compact proportions – you two are going to get a lot of looks!

JEFFSY’s voluminous but light full carbon frame and its compact silhouette already have some observers doubting whether they are actually looking at a 29er. With its aggressive headtube angle, low stand over height and compact chain stays JEFFSY is a player among trail bikes, ready to go fast and get loose in the roughest of terrain. The length of the rear triangle comes optimized for each frame size and ensures a completely new and atypical handling for a 29er.

Thanks to the flip chip technology, JEFFSY’s geometry can be perfectly adapted to different terrain and to your style of riding. The low position gives you a more aggressive headtube angle and a bigger BB drop – perfect for quick and grimy downhill sections. The high position provides a smaller BB drop, so you can blast trails and tight turns with more ground clearance. Our prized Virtual 4 Link suspension technology is present on JEFFSY as well; sensitive, progressive, with lots of mid-travel support. This does not only give you the confidence needed for big gaps and rugged terrain but also makes pedaling a lot more efficient. The tube walls are thicker in critical areas to make sure the frame can handle the abuse, and integrated protectors keep the downtube and chain stays out of harm’s way when the action heats up.

Meet the flagship of the 2017 range: when it comes to the JEFFSY CF Pro Race, it’s all in the name – this premium build is the ultimate weapon for your next race. The super-light e*thirteen carbon wheels were made for the toughest enduro tracks, and the FOX 34 Float Factory fork and the FOX Float X Factory shock will let you tackle any terrain with ease. There isn’t a single component on the CF Pro Race that isn’t ready to line up in the start gate: with carbon handlebars and carbon cranks, SRAM’s Guide Ultimate brakes, and aggressive tires from e*thirteen, you’ll be perfectly equipped for every run.

JEFFSY is exactly the right choice for extended trail rides, for the high alpine, for rocky, rooty terrain and rowdy descents. With tons of traction from the 29“ wheels JEFFSY takes you up any climb, and when it comes time to descend, the bigger wheels provide a smoother ride and better rollover capabilities. JEFFSY is a true weapon on the trail, with lots of gravity potential and appetite for the rough stuff. If your focus is on very aggressive riding and bike park days, you should take a look at our enduro beast, the CAPRA. Those who like to ride their JEFFSY often and hard should check it for damages after every ride, and comply with maintenance and service intervals. That’s the only way you’ll enjoy good times with your best friend for a long time.
